Yoshida J, et al. - In a large Japanese cohort including 40–54 years old 8,153 adults with specific medical checkups done in an Okayama facility from 2009 to 2010 and from 2013 to 2014, researchers evaluated age-adjusted and multivariable-adjusted odds ratios of metabolic syndrome and its components for an average of 3.9 years in relation to night eating habits including dinner immediately before bed, snacks after dinner, or combinations of both. In subjects with both eating habits vs in those with neither habit, the estimated multivariable-adjusted odds ratio for obesity was 2.11 for men and 3.02 for women. Albeit insignificant, a supra-additive interaction influence of both habits on obesity development was seen in women. Women, not men, showed a link between eating habits at night and metabolic syndrome. Men and women both showed an association of both night eating habits with dyslipidemia. Findings call for intervention and awareness among individuals with night eating habits.
